The main objective of this study is to evaluate qualitatively and quantitatively the effect of starvation periods in the biodegradation capacity of microorganisms when the support media is a material with high sorption ...

Monitoring the biological activity in biotrickling filters is difficult since it implies estimating biomass concentration and its growth yield, which can hardly be measured in immobilized biomass systems. In this study, ...

Biofiltration has been established as a promising alternative to conventional air pollution control technologies. However, gas biofilters modeling has been less developed than experimental research due to the complexity ...

Biological techniques for the removal of gaseous pollutants such as hydrogen sulfide
(H2S) have proved to be effective, environmentally friendly, and economically
viable. However, when high concentrations of H2S are ...
